Abstract

In this study, it was aimed to determine the chromosome number of 21 Sal-via L. species, to determine chromosome morphology, to reveal karyotype analysis in detail and to contribute to the cytotaxonomy of Salvia. In this context, the results are as follows: (i) the first report for the number of chromosomes of ten species, namely S. corrugata Vahl. (2n = 16), S. curviflora Benth. (2n = 16), S. darcyi J.Compton, S. greg-gii A.Gray, S. longifolia Nutt., S. vitifolia Benth. (2n = 22), S. subrotunda A.St.-Hil. ex Benth. (2n = 44), S. oppositiflora Ruiz & Pav. (2n = 56), S. stolonifera Benth. and S. atrocyanea Epling (2n = 60); (ii) the karyotypic variations and new chromosome numbers different from previous reports for three species, namely S. cardiophylla Benth. (2n = 36), S. cuspidata Ruiz & Pav. (2n = 44) and S. microphylla Sessé & Moc. (2n = 46); (iii) the same chromosome numbers from previous reports for eight species, namely S. campanulata Wall. ex Benth. (2n = 16), S. elegans Vahl. (2n = 20), S. involucrata Cav., S. mexicana Sessé & Moc. (2n = 22), S. apiana Jeps., S. leucophylla Greene, S. mellifera Greene (2n = 30), and S. splendens Ker Gawl. (2n = 44); (iv) the detailed chromosome measurements and karyotype analyses for all species studied for the first time; (v) the symmetrical karyotypes for all studied species; (vi) the variations resulting from dys-ploidy or polyploidy and discussing their reasons.
